Hop plant named ‘HBC 1019’

ABSTRACT

A new hop plant named ‘HBC 1019’ is disclosed. ‘HBC 1019’ is used for its exceptional and unique aromatic qualities, and is suitable for beer flavoring.

Genus and species: Humulus lupulus.

Variety denomination: ‘HBC 1019’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND OF THE INVENTION

‘HBC 1019’ is a product of a controlled breeding program carried out by the co-inventors in the Yakima Valley of Washington State. ‘HBC 1019’ was one of several seedlings resulting from a controlled cross made in 2016 with female parent ‘HBC 476’ an unpatented variety, and male pollen parent ‘ZRCBM’. ‘ZRCBM’ is a pollen bulk of a multiple of male hop plants, selected for desirable traits including elevated alpha acids, strong vigor, and high pollen shed. Seedling plants from this cross were planted in 2017 and screened for disease resistance and sex in a greenhouse and field nursery near Granger, Wash. A single plant of ‘HBC 1019’ was selected in 2017. In 2018, ‘HBC 1019’ was asexually reproduced and expanded to a seven hill plot. In 2019, ‘HBC 1019’ was asexually reproduced via softwood cuttings near Granger, Wash., and expanded to thirty plants in an evaluation block near Toppenish, Wash. In 2020 ‘HBC 1019’ was further expanded to a two-acre test block near Toppenish, Wash., again with plants asexually reproduced via softwood cuttings. The ‘HBC 1019’ plants have now been observed and evaluated for several years. Throughout several generations of asexual propagation, ‘HBC 1019’ has been observed to retain its distinctive characteristics and remain true to type.

SUMMARY OF THE INVENTION

A new and distinct hop plant is described herein, with the ‘HBC 1019’ cultivar characterized by having cones with high alpha acid and high beta acid content. The new cultivar exhibits sweet fruit, cream caramel, citrus, and floral aromas. The new cultivar is suitable for beer flavoring.

The colors of these illustrations may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED BOTANICAL DESCRIPTION

The following description is based on observations made late in the 2020 growing season at the test block of ‘HBC 1019’ plants near harvest maturity, under typical growing conditions near Toppenish, Wash. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants, of the new variety may vary from the stated average. Color code designations are by reference to The R.H.S. Colour Chart, 4th ed., Copyright 2001, published by The Royal Horticultural Society of Great Britain.
